KDC3225 - 225Amp Circuit Breaker

KDC3225 - 225Amp Circuit Breaker

If you're working on equipment that specifically calls for a KDC3225, having the full breaker specifications at hand makes the replacement process much simpler. The KDC3225 is a 225-amp, three-pole Series C molded-case circuit breaker with a K frame and a T186 trip type. Check the catalog number, frame, trip type, poles, electrical ratings, terminals, and dimensions against the existing equipment. When those details align with the application requirements, the KDC3225 can provide the necessary form, fit, and function. Properly selected, installed, and used within its stated ratings, it's built to last in the equipment it was designed to serve.

Key Features and Benefits

• 225-amp, three-pole breaker: A clearly defined configuration for equipment requiring a 225A, three-pole circuit breaker.
• Complete Series C breaker: Supplied as a complete molded case circuit breaker rather than a frame-only component.
• Type KDC, K frame: Two useful identifiers to check when matching the breaker to equipment already in service.
• T186 trip type: Provides an additional specific reference point to confirm the correct application.
• AC and DC ratings: 600 VAC and 250 VDC.
• Aluminum terminals included: The breaker is configured with line and load terminals made from aluminum.
• 50–60Hz operation: Frequency is clearly specified for application matching.

Where It Works Best

The KDC3225 makes the most sense when you're maintaining existing or legacy electrical equipment that requires this particular KDC breaker configuration. Instead of looking only for another 225A breaker, use the complete specification as your checklist.

Start with the basics: 225 amps, three poles, Type KDC, Series C, K frame, and T186 trip type. Next, make sure the application's voltage and interrupting requirements align with the breaker's 600 VAC/250 VDC rating, 100 kAIC at 480 VAC, and 200 kAIC at 240 VAC.
